Radeon R9 Fury X vs Radeon RX 6900 XT

Intro

The Radeon R9 Fury X comes with a GPU clock speed of 1050 MHz, and the 4096 MB of HBM memory runs at 500 MHz through a 4096-bit bus. It also is made up of 4096 SPUs, 256 Texture Address Units, and 64 ROPs.

Compare that to the Radeon RX 6900 XT, which has a clock speed of 1825 MHz and a GDDR6 memory frequency of 2000 MHz. It also features a 256-bit memory bus, and makes use of a 7 nm design. It is made up of 5120 SPUs, 320 Texture Address Units, and 128 Raster Operation Units.

Radeon R9 Fury X 512000 MB/sec
Difference: 12288 (2%)

Texel Rate

The Radeon RX 6900 XT should be quite a bit (more or less 117%) better at texture filtering than the Radeon R9 Fury X. (explain)

Radeon RX 6900 XT 584000 Mtexels/sec
Radeon R9 Fury X 268800 Mtexels/sec
Difference: 315200 (117%)

Pixel Rate

The Radeon RX 6900 XT is much (more or less 248%) faster with regards to AA than the Radeon R9 Fury X, and also will be capable of handling higher screen resolutions without slowing down too much. (explain)

Radeon RX 6900 XT 233600 Mpixels/sec
Radeon R9 Fury X 67200 Mpixels/sec
Difference: 166400 (248%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Bandwidth is the largest amount of data (in units of MB per second) that can be transported past the external memory interface in one second. It is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
